<< Draft Version 0.002>>

1. Introduction:
    This directory "macbuild" contains different files required for building KLayout
    version 0.25 or later for different Max OSX including:
        * Yosemite    (10.10)
        * El Capitan  (10.11)
        * Sierra      (10.12)
        * High Sierra (10.13)

    By default, Qt framework is Qt5 from Mac Ports (https://www.macports.org/) which
    is usually located under:
       /opt/local/libexec/qt5/

    Also by default, supported script languages, i.e, Ruby and Python, are those
    standard ones bundled with the OS.
    However, you are able to choose other options like Python from Anaconda.

2. How to use:
    (1) Make a symbolic link from the parent directory (where 'build.sh' exists) to
        'build4mac.py', that is,
            build4mac.py -> macbuild/build4mac.py

    (2) Invoke 'build4mac.py' with appropriate options, for example, for debug-build:
            $ cd /where/'build.sh'/exists
            $ ./build4mac.py -d

    (3) Confirm successful build.

    (4) Run 'build4mac.py' again with the same options used in (2) PLUS "-y"
        to deploy executables and libraries under "klayout.app" bundle.
            $ ./build4mac.py -d -y
